Embodiment Construction
[0040] The core of the present invention is to provide a BBU charging device and a BBU. The control module processes the output current of the power supply, the current and voltage for supplying power to the BBU, and then controls the working mode of the voltage conversion module. Since the current output by the power supply is directly detected , the charging response capability is higher, and the working mode of the current voltage conversion module can be better controlled.
[0041] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments It is a part of embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments ...

The invention discloses a BBU charging device and a BBU. The BBU charging device is provided with a first current detection module, a voltage conversion module, a second current detection module, a voltage detection module and a control module. The first current detection module is used for outputting a first voltage representing a current for supplying power to the BBU; the voltage detection module is used for outputting a second voltage representing a voltage for supplying power to the BBU; the second current detection module is used for outputting a third voltage representing the output current of the power supply; the control module is used for calculating a reference voltage according to the second voltage and the third voltage, and controlling the voltage conversion module to convert the voltage output by the power supply according to the third voltage and the reference voltage. The control module processes the output current of the power supply and the current and voltage for supplying power to the BBU so as to control the working mode of the voltage conversion module, and due to the fact that the current output by the power supply is directly detected, the charging response capacity is higher, and the current working mode of the voltage conversion module can be better controlled.
Description
technical field [0001] The invention relates to the field of power supplies, in particular to a BBU charging device and a BBU. Background technique [0002] When charging a backup battery unit (Battery Backup Unit, BBU) in the server, the input voltage is converted by the voltage conversion module, and the converted voltage is used for charging the BBU. When the input voltage is greater than the voltage of the BBU, use the step-down mode to charge the BBU; when the input voltage is lower than the voltage of the BBU, use the boost mode to charge the BBU. figure 1 It is a structural schematic diagram of a BBU charging device in the prior art, such as figure 1 As shown, the device includes a voltage conversion module, a first current detection module, a voltage detection module and a control module, the voltage conversion module is used to convert the voltage output by the power supply, and the first current detection module is used to output the current represented as the BBU...
